Spawning Multiple Templates using XObject

[bev_s]

I have two template pages that are spawned successfully 1 time each with this code I extracted from the SDK:

var a = this.templates;

   for (i = 0; i < a.length; i++)

      a[i].spawn(this.numPages, false, false);

Unfortunately the file size became rather large with multiple spawns, so I then tried to generate them as XObjects using the code also found in the SDK as it indicated it could reduce filesize; I tweaked the code below to only spawn one time by changing the 30 to a 1. 

   var t = this.templates;

   var T = t[0];

   var XO = T.spawn(this.numPages, false, false);

   for (var i=0; i<30; i++) T.spawn(this.numPages, false, false, XO);

The problem I am having is that it only recognizes one of my two templates and never spawns the second one. I have tried several different things -- all found on the internet and in the SDK as I'm quite the learner at this -- and have been completely unsuccessful. Any guidance on what I am doing incorrectly would be greatly appreciated - thank you!

It's not entirely clear what you want to accomplish, but if you want to spawn template #1 and then template #2, and repeat that 30 more times, the code could be:

var aTemplates = this.templates;
var T1 = aTemplates[0];
var T2 = aTemplates[1];
   
var XO1 = T1.spawn(this.numPages, false, false);
var XO2 = T2.spawn(this.numPages, false, false);

for (var i = 0; i < 30; i++) {
    T1.spawn(this.numPages, false, false, XO1);
    T2.spawn(this.numPages, false, false, XO2);
}

That was exactly what I needed - thank you so much! ❤️

This will have no effect on the file-size, though. It only makes the code work faster.

[George_Johnson]

It should have a big effect since the page contents (text, images, vectors) of those 30 additional pages are not stored separately in the file.

[try67]

If you use Save As after spawning it does the same, I believe.

[George_Johnson]

No, and it would be wrong if it did.

Why want you 30 versions of the same pages?

[bev_s]

In my post, I indicated that I copied the code from the SDK, which was written to spawn one page 30x (you can ask them why they wanted 30 of the same page 😛 ) , but that I tweaked the code to only spawn one time, which was what I needed. I don't need 30 of the same page, but two pages spawned at a time. Eventually it would grow to total 60 pages, however, as it is an online journal in which a person spawns two pages per day for a month to write in their journal.

George's code worked perfectly and he is correct - in my testing of the code without using XObject, when I spawned all 60 pages, the file size was about 80MB; when I changed the code to use George's XObject code, the file size shrunk to 6.5MB. A big difference!

Why want you two pages per day with the same content?

[bev_s]

It's an interactive journal - you write in it every day. Each day the user wants to write in their journal, they spawn a new writing template.
